FEATURES

 

Delivering both the most beautiful bokeh and outstanding resolution.

Beautiful feathered bokeh from the maximum F1.2 aperture


Competitor product of equivalent specifications :
Each flower petal has its own individual bokeh.

 


M.Zuiko Digital ED 17mm F1.2 PRO at f/1.2 : 
The bokeh of the flower petals blend together

The M.Zuiko Digital ED 17mm F1.2 PRO delivers beautiful feathered bokeh that blends the image from focused sections to out-of-focus sections and provides a smooth impression to the defocused background, providing more depth to the image by making the subject stand out further.

 

Beautiful feathered bokeh made possible by an ultra-high precision aberration measurement instrument

Beautiful feathered bokeh was achieved thanks to an ultra-high precision aberration measurement instrument developed incorporating high-precision measurement technologies used in advanced microscope development. This measurement instrument was used in research stages to measure the characteristics of historically acclaimed lenses, which would become the base for newly developed lenses. In development stages, the instrument was used to create a lens design that optimizes the level of aberrations, while virtually eliminating all unwanted aberrations.

The M.Zuiko Digital ED 17mm F1.2 PRO adopts a design which intentionally guides light beams passing on the outside edges of the lens to form an image in the foreground, while gradually tilting the lens as the spherical aberration moves towards the outside edge. Intentionally keeping spherical aberrations results in beautiful feathered bokeh.

 

High resolution from lavish use of special lenses

This lens employs 6 ED lens elements, the most of any M.Zuiko lens, including the newly developed ED-DSA lens, which incorporates the features of both ED (Extra-low Dispersion) and DSA (Dual Super Aspherical) lenses. This construction effectively compensates for unfocused colour bleeding (axial chromatic aberration) which is a common problem on large-diameter lenses, and colour bleeding (magnification chromatic aberration) at the image periphery. It also contributes to creating beautiful feathered bokeh, and achieving superb optical performance which accurately represents points as points even at the widest aperture setting.

The ED-DSA lens which uses ED glass on a DSA lens has been successfully mass-produced for the first time ever by Olympus. This lens delivers the excellent chromatic aberration correction abilities of the ED lens and the spherical aberration, comatic aberration, and astigmatism correction abilities of the DSA lens in a single lens. Incorporating the ED-DSA lens significantly reduces the number of lens elements, resulting in a shorter overall length of the lens body while providing higher performance.

Excellent close-up shooting ability

 Closest Focusing Distance: 20 cm

This lens has excellent close-up shooting abilities with a closest focusing distance of 20 cm, and shooting magnification of 0.15x (35mm equivalent: 0.3x). You can get closer to subjects to emphasize background bokeh.

 

Z Coating Nano for clear image quality


1. Air / 2. Nanoparticles / 3. Incident light / 4. Reflected light / 5. Lens / 6. Vapour deposit film

Coating technology is employed which coats the lens surface with a layer of nanoscale size particles that have air in the centre, resulting in a coating with a similar refractive index as air and reduced surface reflection. Ghosts and flaring are significantly reduced for sharp, clear image quality.

 

Fast & high-precision AF

MSC mechanism making fast and silent AF possible

 1. Focusing lens


1. Stepping motor
2. Screw drive
3. Shaft

Despite being a large diameter F1.2 lens, a lightweight focusing unit is made possible via the MSC (Movie & Still Compatible) mechanism. A screw drive mechanism is used as the core drive system of the MSC mechanism, and a stepping motor is used as the drive motor.

 

High-precision AF across all focusing points

 DSLR (Phase detection AF)
Current SLRs are limited to F2.8 light fluxes. Because there is no sensor for focusing at F1.2 light fluxes, AF precision is not guaranteed when a lens brighter than F2.8 is attached.

 OM-D E-M1 Mark II (On-chip Phase detection AF)
On-chip Phase Detection AF has no light flux limitations, making high-precision focusing with all-cross AF possible even when a large-diameter F1.2 lens is attached.

On-chip Phase Detection AF used on the OM-D E-M1 Mark II has no light flux limitations, making all-cross AF possible even when a large-diameter F1.2 lens is attached. This provides coverage for the all focusing points to the edges of the image for high-precision focusing.

 

Eye Priority AF demonstrates its power during portrait shooting

When used in conjunction with Eye Priority AF on the OM-D E-M1 Mark II, it is possible to capture portraits that are sharply focused on the subject’s eyes.

 

Excellent mobility

Amazingly compact, lightweight system

 Approx. 1,700 g (Camera Body Full-frame DSLR + 35mm Competitor)

 Approx. 964 g (OM-D E-M1 Mark II + M.ZUIKO DIGITAL ED 17mm F1.2 PRO)

This large-diameter, maximum aperture F1.2 lens is compact and lightweight. It is approximately 390 g, and when paired with the OM-D E-M1 Mark II it creates an amazingly compact lightweight system at only approximately 964 g.

 

Reliable dustproof, splashproof, and freezeproof construction

Hermetic sealing across the entire lens results in highly reliable dustproof, splashproof, and freezeproof performance. You can feel comfortable shooting anywhere, never worrying about dust, rain, or inclement weather.

 

Others

Controls that meet the demands of pros

 The focus ring is wider and placed towards the front of the lens barrel making comfortable focusing possible even when paired with the OM-D E-M1 Mark II.
1. Focusing

 The L-Fn button is positioned along the edge of where the concave design ends, making it easy to locate even with your eye to the viewfinder.

 The focal length display is larger for easier identification.

 The Manual Focus Clutch mechanism makes instant switching to manual focus possible by pulling the focusing ring towards you.
1. Distance scale

Controls are designed to meet the demands of pros, including a focus ring which provides for comfortable focusing, and an L-Fn button which can be operated as you keep your eye to the viewfinder.

 

Optional lens accessories

LH-66C Lens Hood

This is a lens hood which can be attached to the M.Zuiko Digital ED 17mm F1.2 PRO lens. The hood release section has been modified so that the lens hood cannot be unintentionally removed.

Depth of field

When focusing on a subject, there is an area behind and in front of the focused point that is also in focus. This area is called depth of field. The amount of area behind a focused point will always be greater than the area in front of the focused point regardless of aperture. Depth of field becomes deeper when the focal length is short (wide-angle lens), the focusing distance is long, and aperture is small.
